我一直在尝试从我的ajax查询中添加数据，该查询返回以下模式创建的json数据： $ lastedited = $ _GET ['lastload'];
$count = 1;
$JsonArray = Array();
while ($count <= 4) { // luupataan x määrä ellei vastauksia tule.
$result = mysql_query("SELECT RFQs.DateAdded as DateAdded,
Customers.Name as customer,
RFQs.ID as RFQID,
Suppliers.Name as supplier,
Ships.Name as ship,
RFQs.CustomerRef as CustomerRef,
Contacts.FirstName as contactF,
Contacts.LastName as contactL,
Contacts.Email as contactE,
Users.tunnus as handler,
RFQStatus.Name as status,
RFQs.Description
FROM RFQs
LEFT JOIN Ships ON RFQs.ShipID=Ships.ID
LEFT JOIN Contacts ON RFQs.ContactID=Contacts.ID
LEFT JOIN Customers ON RFQs.CustomerID=Customers.idCustomers
LEFT JOIN Users ON RFQs.PriJobHandler=Users.id
LEFT JOIN Suppliers ON RFQs.SupplierID=Suppliers.ID
LEFT JOIN RFQStatus ON RFQs.StatusID=RFQStatus.ID
WHERE RFQs.LastEdited > '$lastedited'
") or die(mysql_error());
if (mysql_num_rows($result) == 0) {
$count++;
sleep(5); // ei uusia rivejä, nukutaan 5 sekuntia ja yritetään uudelleen.
}else {
// käy rivit läpi ja pistää arrayyn
for ($x = 0, $numrows = mysql_num_rows($result); $x < $numrows; $x++) {
$row = mysql_fetch_assoc($result);
array_push($JsonArray, array("rivi" => array("ID" => $row["RFQID"],
"DateAdded" => $row["DateAdded"],
"Supplier" => $row["supplier"],
"Customer" => $row["customer"],
"Ship" => $row["ship"],
"CustomerRef" => $row["CustomerRef"],
"Contact" => $row["contactF"]." ".$row["ContactL"],
"Description" => $row["Description"],
"PIC" => $row["handler"],
"Status" => $row["status"])));
}
$count = 6;
}
}
if ($count == 5) {
echo "NO RESULTS!!";
}
else if ($count == 6) {
//echo JSON to page
echo json_encode($JsonArray);
}
我的jQuery是这样的：
<script type="text/javascript" charset="utf-8">
function waitForMsg(lastload){
if (lastload==null){
lastload = { "lastload": "<?php echo $lastload; ?>" };
}
$.ajax({
type: "GET",
url: "GetUpdates.php",
datatype: "json",
data: lastload,
async: true, /* If set to non-async, browser shows page as "Loading.."*/
cache: false,
timeout:50000, /* Timeout in ms */
success: function(data){ /* kun tulokset saadaan niin suoritetaan.. */
if (data=="NO RESULTS!!") {
setTimeout(
'waitForMsg()',
1000
);
} else {
displayrow(data.rivi);
}
},
error: function(XMLHttpRequest, textStatus, errorThrown){
addmsg("error", textStatus + " (" + errorThrown + ")");
setTimeout(
'waitForMsg()', /* Try again after.. */
"15000"); /* milliseconds (15seconds) */
},
});
};
$(document).ready(function(){
waitForMsg(); /* Start the inital request */
});
function displayrow(item)
{
var tblRow =
'<td id="showbutton-'+item.ID+'"><a href="#" onclick="hideShow(rowID'+item.ID+'">+</a></td>'
+'<td id="DateAdded-'+item.ID+'">'+item.DateAdded+'</td>'
+'<td id="Supplier-'+item.ID+'">'+item.Supplier+'</td>'
+'<td id="Customer-'+item.ID+'">'+item.Customer+'</td>'
+'<td id="Ship-'+item.ID+'">'+item.Ship+'</td>'
+'<td id="CustomerRef-'+item.ID+'">'+item.CustomerRef+'</td>'
+'<td id="Contact-'+item.ID+'">'+item.Contact+'</td>'
+'<td id="Description-'+item.ID+'">'+item.Description+'</td>'
+'<td id="PIC-'+item.ID+'">'+item.PIC+'</td>'
+'<td id="Status-'+item.ID+'">'+item.Status+'</td>'
+'<td id="Actions-'+item.ID+'">Hit F5 for actions</td>';
$('#newRFQrowInput').before(tblRow);
}
</script>
问题是我不确定如何处理从ajax查询返回的数据。 目前我所得到的都是未定义的。
有人能帮忙吗？
谢谢！

在发送回信息的.php文件中进行更改
$JsonArray = array("ID" => $row["RFQID"],
"DateAdded" => $row["DateAdded"],
"Supplier" => $row["supplier"],
"Customer" => $row["customer"],
"Ship" => $row["ship"],
"CustomerRef" => $row["CustomerRef"],
"Contact" => $row["contactF"]." ".$row["ContactL"],
"Description" => $row["Description"],
"PIC" => $row["handler"],
"Status" => $row["status"]
);
echo json_encode(array('rivi'=>$JsonArray));
<强>更新
在你的＆＃34; For循环＆＃34;
中进行更改$JsonArray = array();
for ($x = 0, $numrows = mysql_num_rows($result); $x < $numrows; $x++) {
while($row = mysql_fetch_assoc($result)){
array_push($JsonArray,array("ID" => $row["RFQID"],
"DateAdded" => $row["DateAdded"],
"Supplier" => $row["supplier"],
"Customer" => $row["customer"],
"Ship" => $row["ship"],
"CustomerRef" => $row["CustomerRef"],
"Contact" => $row["contactF"]." ".$row["ContactL"],
"Description" => $row["Description"],
"PIC" => $row["handler"],
"Status" => $row["status"]
)
);
}
}
将此替换为你的
else if ($count == 6) {
//echo JSON to page
echo json_encode(array("rivi" =>$JsonArray));
}
并且在ajax成功功能中也是如此。
success:function(data){
if(data.rivi.length){
//alert(data.rivi.length);
displayrow(data.rivi);
}
}
然后在你的displayrow函数
中function displayrow($item){
var tblRow = '<table>';
$.each($item,function(index,value){
tblRow +='<tr><td id="showbutton-'+value.ID+'"><a href="#" onclick="hideShow(rowID'+value.ID+'">+</a></td>'
+'<td id="DateAdded-'+value.ID+'">'+value.DateAdded+'</td>'
+'<td id="Supplier-'+value.ID+'">'+value.Supplier+'</td>'
+'<td id="Customer-'+value.ID+'">'+value.Customer+'</td>'
+'<td id="Ship-'+value.ID+'">'+value.Ship+'</td>'
+'<td id="CustomerRef-'+value.ID+'">'+value.CustomerRef+'</td>'
+'<td id="Contact-'+value.ID+'">'+value.Contact+'</td>'
+'<td id="Description-'+value.ID+'">'+value.Description+'</td>'
+'<td id="PIC-'+value.ID+'">'+value.PIC+'</td>'
+'<td id="Status-'+value.ID+'">'+value.Status+'</td>'
+'<td id="Actions-'+value.ID+'">Hit F5 for actions</td></tr>';
}
tblRow = '</table>';
$('#newRFQrowInput').before(tblRow);
}

在页面末尾写下echo json_encode($JsonArray); GetUpdates.php
如果您使用的是 GET 方法，那么我建议您使用$.getJSON
您的数据就是这样
[{rivi：{ID：23，DateAdded：2012-02-10，...}}]
所以我为你做了一个例子，休息只是逻辑
var jsonData = [{rivi:{ID:'23', DateAdded:'2012-02-10'}}];
alert(jsonData[0].rivi.ID); // will return 23
答案 2 :(得分：0)
你做完了吗
json_encode( $JsonArray );
返回之前？
echo $JsonArray
